The father of a 14-year-old girl is making allegations against a teacher's aide.

Macy Garner says 19-year-old John Isaac, a teacher's aide at Franko Middle School, solicited sex from his daughter via the Internet. Garner says his daughter had been in contact with the teacher's aide, but that it went to far when he solicited sex and showed up at his home.

Isaac was questioned by Mount Vernon detectives Friday night. The teacher's aide now faces charges of endangering the welfare of a child and aggravated harrassment.

Macy Garner tells News 12 Westchester that since school let out Friday afternoon, his family has not heard from his daughter.

If you have information regarding the whereabouts of Macy Garner's daughter, you are asked to contact Mount Vernon police.
